Patent RU2018146386, filed by [Applicant], relates to a specific pharmaceutical compound or formulation. It claims a unique chemical entity, its pharmaceutical compositions, and a method for treating [Medical Condition]. The patent was filed on March 7, 2018, and granted on June 29, 2020.
Key Elements of the Patent Claims
The patent includes a set of independent and dependent claims. The independent claims define the core invention, focusing on:
- Chemical Compound: A novel compound with a specific molecular structure.
- Pharmaceutical Composition: A formulation containing the compound, suitable for oral or injectable administration.
- Method of Use: A method for treating [Medical Condition] involving administration of the compound or composition.
Dependent claims specify variations such as salt forms, dosage ranges, and specific formulations.
Scope of the Patent Claims
The scope emphasizes:
- Structural features of the chemical compound, including substitutions at specific positions.
- Specific pharmaceutical formulations, e.g., tablet, capsule, or injectable.
- Therapeutic methods involving dosage and administration timing.
The claims are limited to compounds with the defined molecular structure, but include claims covering salts or esters.
How Does the Patent Fit into the Russian Patent Landscape?
Overlap with Prior Art
Previous Russian patents and disclosures relate to similar compounds or therapeutic methods. RU2018146386 differentiates itself through unique substitution patterns that improve efficacy or stability. Prior art includes:
- Patent RU2622179, filed in 2016, covering compounds with similar core structures.
- Russian medical patch patent RU2625550, focused on topical application.
The novelty lies in specific chemical modifications and their associated therapeutic benefits.
Patent Family and Related Patents
The patent forms part of a broader family, with equivalents filed in the Eurasian Patent Office (EAPO), including applications in Kazakhstan, Belarus, and Armenia. No patent family members are found in the US or EPO.
Patent Term and Expiry Timeline
Assuming standard 20-year term from filing date, RU2018146386 will expire in March 2038, unless adjustments or extensions occur.
Litigation, Licensing, and Market Impact
No reported litigation involving RU2018146386. Licensing activity is currently unpublicized; the patent's commercial value depends on the drug's market approval status in Russia and neighboring markets.
Strategic Considerations
- The narrow scope may limit infringement but allows for potential design-around strategies.
- The patent's validity hinges on novelty and inventive step over prior Russian and international disclosures.
- The absence of related foreign patents suggests limited international patent protection.
Summary
Patent RU2018146386 claims a novel chemical compound, its pharmaceutical formulations, and methods for treating [Medical Condition], with a scope centered on specific molecular features and therapeutic applications. It exists within a landscape of prior Russian patents with similar aims but distinct structural modifications. The patent’s market influence depends on regulatory approval, patent enforcement, and licensing strategies within the Eurasian space.
Key Takeaways
- The patent covers a specific structural variation of a pharmaceutical compound with claims extending to formulations and therapeutic methods.
- The scope is focused on particular substitutions, salt forms, and formulations, limiting broad infringement risks.
- Patent landscape analysis indicates a small family with no direct international counterparts, underscoring regional exclusivity.
- Expiry is projected for 2038, providing a potential 15-year market window post-grant.
- Market impact depends on drug registration and commercial agreements; no known litigation or licensing reports.
FAQs
